R28-8B1 FDT TYPE HIWIN PRECISION GROUND BALLSCREWS
FEATURES
Low noise (lower 3~5dB than general series)
Finest design of recirculation can absorb noise from the impact of balls to reduce noise level.
Qualified tone
Super T recirculating components not only can reduce the sound pressure level, but also efficiently lower the middle and high frequency range better than conventional ballscrews, producing no shrill fricative and better sound quality.
Low vibration and smooth operation
The tangent recirculation substantially reduces impact force of running balls and the resistance of guiding balls, so the vibration of the nut is gentler and the rotation is smoother and more stable.
APPLICATIONS
CNC machinery, precision machine tools, industrial machinery, electrical machinery, high speed machinery.
